Mittag-Leffler Institute

The Mittag-Leffler Institute of the Royal Swedish Academy of Sciences in Stockholm is a research institute for mathematics. It was founded in 1916 by Gösta Mittag-Leffler, who ( along with his wife Signe ) for his villa ( from the years 1890-1906, with parking and ancillary buildings) and his mathematical research library set are available. Since 1919 it is affiliated to the Swedish Academy, in his direction but largely independent.

Mittag-Leffler had the late 19th century and early 20th century an important role in the international community mathematicians, including as founder of Acta Mathematica ( 1882), and because of its good links with both French and German to mathematicians.

Mittag-Leffler was a wealthy businessman and was initially able to make sufficient funds available for a stock market slump in 1922 but dwindled the means, and at lunch Leffler's death in 1927 he was himself and the Institute bankrupt. Initially, the Institute was then headed by Torsten Carleman, who lived in the villa and a professor at the University. The Institute was then essentially only from the library. Even after the death of Carleman in 1949 did not change much until it was revived by Lennart Carleson 1969. With financial support from the Wallenberg Foundation and by insurance companies, the Institute was expanded. Carleson was until 1984 the director.

Director until 2010 Anders Björner, Professor of Mathematics ( Combinatorics and specialist ) at the Royal Institute of Technology ( KTH ) in Stockholm. Since 2011, Ari Laptev is the director.

The Institute is dedicated to every year or one semester a mathematical specialty and invites leading scientists one together with those from Scandinavia. They see themselves as a research institute for the entire Scandinavian countries and is supported also from Denmark and Norway.

The Institute is in addition to the Acta Mathematica Journal Arkiv för Matematik (founded in 1903) out.

The headquarters of the Institute is in Djursholm ( Auravägen 17), a residential suburb 10 km north-east of the center of Stockholm.
